The Leupold® Tactical Milling Reticle (TMR®) The Leupold® Tactical Milling Reticle (TMR®) and Horus H27 reticle employ a system based on the subtension of one milliradian (mil) from the center of one full hash mark to the center of the next full hash mark. This subtension also applies from the center of the reticle to the center of the first full hash mark in any direction.
3 TMR reticle offers areas of .2 mil subdivisions to precisely measure the common one meter target quickly from 500 to 1,000 meters and beyond. This has previously been the most difficult task in long-range shooting, since this entire range lies in the span between one and two mils. The position of the .2 mil subdivisions are intentionally placed on the periphery of the fine crosshair in order to keep the central area clutter free.
Parts of the Leupold TMR and Horus® H27 Reticles A milliradian is a unit of measure derived from the degrees of a circle (in a 360 degree circle, there are 6,283.2 milliradians, or 17.45 milliradians per degree.) This means that a milliradian will subtend different amounts at different ranges. For example: The subtension of 1 mil equals 3.6 inches (3.44 MOA) at 100 yards or 36 inches at 1,000 yards. In metric units, the correspondence is 1 mil equals 10 centimeters at 100 meters or 1 meter at 1,000 meters.
5 The scale can be visually subdivided and/or combined by a trained user to produce infinite milliradian reference combinations for limitless target ranging, leading, or holdover precision. Since the holdover features are presented in milliradian increments, they can be correlated to any ballistic trajectory or used to estimate windage and lead moving targets in the same manner as all milliradian based reticles.
THE USE OF A TMR OR H27 RETICLE To use the TMR or H27 reticle, you must know the actual size of the target. 1. View the target through the scope. 2. Place the center of the crosshair against one edge (top, bottom, or either side) of the target so that the crosshair extends along either its width or height. 3. Using the hash marks, measure along the crosshair to the opposite edge of the target.
7 (Height of Target in Yards x 1,000) ÷ Height of Target in Mils = Range of the Target in Yards This formula will also give results in metric terms if meters instead of yards are used in the equation. For your convenience, Leupold has included range estimating tables (see Tables 1-8). To use these tables, locate the actual size of the target along the top of the table and the apparent size of the target, as measured in mils, along the side of the table. Follow both until they converge.
Using the Data Obtained With the Tactical Milling Reticle or H27 Once you have estimated the distance to the target with the reticle, there are two primary methods of using this information. Both require that you know the specific bullet drop of the ammunition you are using, measured in milliradians. If your bullet drop has been measured in inches, a conversion to MOA will need to be applied using the formula below. (Bullet Drop in Inches ÷ 1.
9 Example 1: If you have a 500 yard/meter shot and you know your bullet drops 65 inches at that distance, you would follow the steps below: Convert 65 inches to MOA: (65" ÷ 1.047) = 62 5 5 Convert MOA to mils: 12.4 MOA 3.44 MOA per mil = 12.4 MOA = Bullet drop in mils = 3.6 This bullet would be dropping 3.6 mils at 500 yards. Example 2: If your bullet drops 130 Inches at 650 yards/meters, the process would look like this: (130" ÷ 1.047) 6.5 = 19 MOA 3.44 MOA per mil 124 6.
DIALING THE CORRECTION INTO THE SCOPE The most effective way to use the estimated distance is to dial the necessary correction into the scope using the elevation adjustment. If your scope features a bullet drop compensation dial, simply dial the correction directly according to the distance marked on the elevation dial. If your scope does not have a bullet drop compensation dial and your bullet drop has been measured in milliradians, simply use the elevation adjustment to make the appropriate correction.
